Similar reference characters refer to similar parts throughout the several views of the drawings.

Having reference now to the drawings, and more particularly to FIGURES 1 to 5, inclusive, one form of device incorporating features of the instant invention is generally indicated at 30 and comprises an outer collapsible tube 31 which is basically concentric with an inner collapsible tube 32. Inner tube 32 has a frusto-conical upper portion 33 which terminates in a cylindrical mouth 34 around which are spaced longitudinal ribs 35. The outer tube 31 has a frusto-conical portion 36 which terminates in a tubelike nozzle 37, on the inner side of which are a plurality of veins or grooves 38 which define channels. In the modification shown in FIGURE 2, the grooves are helically or spirally arranged, and of generally rectangular cross-section as shown in FIGURE 3. The grooves may be relatively narrow and straight as indicated at 380 in FIGURE 4 contained within a nozzle 37a substantially identical otherwise with the tube or nozzle 37, or may be rectangular and straight as shown at 38b in FIGURE 5. Other suitable shapes may be employed so that when material of different colors such as indicated at 39 and 46 contained in the outer and inner tubes, respectively, is extruded, there will be a core 40a of one color, which in the absence of elements to be described hereinafter, will be striped with stripes of a different color, that of the material 39, the stripes being either straight or helical in accordance with the grooving, and of a variety of sizes.

An adaptor 41 having a skirt 42, a frusto-conical portion 43, and a nozzle or tube 44 may overlap the nozzle 37. When this is employed, since the nozzle 44 is substantially the same diameter as the inner diameter of nozzle or tube 34, a core 40a comprised of the contents 40 of the tube 32 will be extruded which will be completely coated by a coating 45 of a different color which will be extruded from the contents 39 of tube 31, the coating being effected bythe meshing and diffusing of the raised stripes caused by the grooves 38, 38a, or 38b into and around the core material lilo.

Obviously, the grooves 38 may be of any desired shape, either halt round, square, or rectangular, or triangular, the interior of the adaptor although normally smooth may be arranged with additional grooves to provide a cliifusion and includes a frusto-conical portion 56 terminating in a nozzle 57 of tubular construction which is also provided with a shoulder 58, both externally and internally. The internal shoulder 58 seats on the shoulder 54. The inner surface of nozzle 57 may be provided with ribs or grooves 58, which will impart a design of pastelike material within the tube to the exterior of a core comprised of pastelike material extruded from tube 51.

An outer tube 6t) has a irusto-conical top section 61 and a tubular nozzle 62, the interior of which is provided with ribs 63, the lower extremities of which seat on the external portion of the shoulder 58, the ribs 63 defining grooves or veins through which a still dilferent color of pastelike material contained within the outer tube may be extruded. It will be seen that a wide variety of designs may be achieved, since the grooves or veins or this modification may take any of the shapes of the previous modification. An adaptor 65 similar to the previously described adaptor 41 may also be employed and includes an outer shell 66 having an offset portion 67 with an internal shoulder 68, the latter seating on the top of shell or nozzle 62. Adaptor 65 may be employed in exactly the same way as the adaptor 41 of the previously described modification. The use and operation of this device is the same as that previously described except that there are here three tubes having three different colors of material rather than the two previously described.

Still another form of the invention is shown in FIG- URES 11 to 15, inclusive, and is generally indicated at 7 0. This form includes an inner tube 71 having a frustoconical top 72 and a tubular nozzle 73. An outer tube 74 has a frusto-conical portion 75 and a nozzle portion 76 concentric with and of the some length as the nozzle 73,

103 with the depending skirt portion 106 seating in the recess 105. Any desired arrangement of internal grooves, of any of the shapes previously described in either helical or straight may similarly be employed with this modification of the invention, so that a wide variety in diffusion, shapes and sizes and colorings of semi-solid material may be extruded from two, three, or more concentric tubes or the like.

Obviously, any desired arrangement of grooves or ribs in accordance with the preceding modifications may herein be employed also.

In FIGURE 21 there is shown a neck 110 of an external tube 111, which may comprise the outermost of a series of concentric tubes of any of the forms previously described, which is provided with a plurality of threads 112 adapted to engage corresponding internal threads 113 on a closure cap 114 which simultaneously closes all of the exit tubes. A space is provided for an adaptor 115 which may be similar to any of the previously described forms of adaptors.

In the foregoing the several nozzles have been described as integral with related concentric tubes. It will, however, be understood that they may be detachably applied to individual tubes during manufacture, or under other such conditions as may be desirable.

FIGURE 22 discloses a concept of this invention which may be employed with pressurized cans. In this form of the invention a conventional pressurized can is indicated at 129 provided with a sealed top 121 and a tiltable nozzle 122 having an internal valve 123 which, when the nozzle or stem 122 is tilted, serves to release the pressurized contents of the container 120. A threaded extremity 124 is provided on the stem 122 which is adapted to engage in M a threaded nut 125 in the concaved bottom 126 of a conthe inner surface of which is squared and provided with vanes or grooves 77. An outer tube 78 has a irustoconical portion 79 which terminates in a tubular section 80 which is reduced in diameter as at 81 and has a plain external reducing spout or nozzle 82. Interiorly of the portion 80 a plurality of grooves or vanes 83 are provided which again may be of any desired shape as in the previous modification. A wide variety of stripings may similarly be produced with this form of the invention, and if desired, an outer adaptor may similarly be employed over the reducing nozzle 82.

In the form of the invention disclosed in FIGURES 16 to 20, there is generally indicated at 99 a device constructed in accordance with this modification comprised of an inner tube 91 having a tapered or frusto-conical portion 2 terminating in a tubular nozzle 93 which is provided with an external shoulder W1. A second tube 95 is concentrically positioned relative to tube 91 and has a frusto-conical top 96 which terminates in an upright portion 97 having a tubular nozzle 98. Interior ribs or vanes 99 seat on'shoulder 94 while an external shoulder 11% is also provided. An outer tube m1 has a frustoconical portion 1112 which terminates in an upwardly extending nozzle 1&3 having internal ribs or vanes 1M- which rest on shoulder 1%. The top of nozzle 163 is recessed as at 195 to accommodate the internal flange 1% of an adaptor or outer nozzle 1&7 which is provided with an annular shoulder 11% which seats on the top of member tainer 127. Container 127 has two or more internal concentric chambers 128 and 129 formed therein, the bottoms of which are closed by a horizontal bafiie 130 which extends transversely across the container above the nozzle 122.

The annular baftle 3% is provided with a series of annular rings or perforations 131, 132, and 133 which extend respectively into the chambers formed by the interior walls. Each of the chambers defined by the internal walls contains a semi-solid medium respectively designated as 134, 135, and 136, each ofwhich is of a different color. A concaved reversed depression 137 is positioned centrally of baffle 131 directly above the outlet of nozzle or tube 122 so that gas under pressure from container 129 is distributed evenly and enters all of the chambers defined by the walls 127, 128, and 129 equally. Any of the nozzles described in any of the foregoing types of construction may be employed in conjunction with the containers 127, 128, and 129 to provide any of the diffused patterns of the previously disclosed modifications.

From the foregoing it will now be seen that there is herein provided an improved dispensing device which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiments hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted as illustrative, and not in a limiting sense.
